5 Installation Instructions
For KX-NT343/KX-NT346
The KX-NT303/KX-NT305 allow 12/60
additional CO buttons to be connected to this unit. These
buttons are used to seize an outside line, make a call using
One-touch Dialing, or perform a feature that has been
assigned to the key.
To prevent damage to the telephone, be sure to unplug
the extension line before you install or uninstall the
Add-on Key Module.
